[" If "A+B-C=3 pi," then "sin A+sin B-],[" sinC is equal to- "]

If A+B-C=3 pi, then sin A+sin B-sin C is equal to -

IfA+B-C=3 pi then sin A+sin B-sin C is equal to

If A+B+C=pi , then sin2A+sin2B-sin2C is equal to

If A+B=(pi)/(2) and sin A+sin B=1 then sin2A is equal to

In triangle A B C if sin A sin B sin C is equal to 10^(-3) and (A B)(B C)(C A) is equal to 10^3 then the area of triangle A B C , is
